cesium downloads sky map tiles on demand and loads them offline
Usage scenarios In some specific needs, tile resources need to be deployed offline. At this time, the online tile service cannot meet such needs, so the tile images need to be loaded. This advantage is that there is no need to deploy tiles in the background. The tile service does not need to rely on […]

3Dtiles file organization method based on b3dm
It was the second time before May 1st that I encountered the need to generate 3dtiles independently to display the 3d model in cesium. This time, when realizing this requirement, I found that there were many deficiencies in the understanding of the 3dtiles format. Taking advantage of the Dragon Boat Festival Record these understandings during […]
